See that search box in the upper right corner? Typing "xmms" there will quickly reveal the "xmms now available" and "XMMS for N900?" threads. Even if you don't see the box, googling for "xmms maemo" will quickly yield results.

Please don't waste other people's time by being too lazy to search for things. And if you don't find something, just create another thread. Thanks (Please don't feel offended by this post, I'm just trying to help.)
